Department of Chemistry Faculty of Science Mu'tah University Al-Karak, Jordan (+)- Electrospray mass spectrometry ionization interlace is a powerful tool in determining molecular weight of large, non-volatile or polar organic compounds. Mass analysis of three different azine derivatives 1-3, recently prepared in our lab., was conducted using LCDuo ion-trap quadruple LC-MS equipped with (+) - electrospray ionization interface. Molecular ions observed were [M]+, [MH]+ as well as dimers, sodium and potassium adduct ions for the three compounds. Keywords : LC- MS,BICYCLIC AZINE N ALLYL PYRAZOLE, TETRAENE AZINE
